The U.S. has announced new sanctions against multiple North Korean individuals and companies for “illicitly” raising money for Pyongyang’s weapons programs, including two DPRK citizens previously accused of laundering money through the Democratic Republic of Congo (DRC) and an art studio operating in Africa.

In a press release published Wednesday, the Department of the Treasury’s Office of Foreign Assets Control (OFAC) listed new designations against Hwang Kil Su and Pak Hwa Song, as well as the DPRK firms Chilsong Trading Corporation, Korea Paekho Trading Corporation and Congo Aconde SARL.
